Sub_title: Trying to use puppy on old classroom computers.
 

Hey guys. Newbie here in two regards: 1) New to linux (and therefore puppy) and 2) This is my first post to a discussion forum. I apologize in advance for any mistakes in forum etiquette I may make. Any help I recieve here will be greatly appreciated.

I have recently made a boot disk and test drove puppy 5.2 on an old gateway laptop. I like the OS and I think it will work nicely on old computers in my classroom. I have a specific need for students to be able to view a couple of different websites and possibly work in google docs. I think puppy can get this done.

Problem: I need to be able to lock the background, icons, limit websites, uninstall games and all the normal "teacher" administrative tasks. I know these are probably easy tasks, but being new to linux I don't know where to start. Networking the stations together would be a plus, but not a necessity.

Preferred solution: Guide me through the steps to follow to disable or limit certain features. Networking tips are fine to. Links to websites or documentation are fine, as I am fairly competent at following directions.

Alternate solution: Guide me to a version of puppy that has network/internet capability, firefox (flash capable), optional word processor and nothing else for any of my students to tamper with. (i.e. no graphic options, no games, no password menus to lock down student users)

Thanks in advance for any help. I apologize for my ignorance, but I believe this could be a great OS for reviving some dead computers around our school if I can limit some parameters for my students.

Maybe you should give more precise technical detail about your hardware.

Puppy is mainly "root" : root is somehow the name for the admin . It is possible to use the "dummy" user "spot" but spot's directory is located at /root . Passwords and group files are
/etc/shadow
/etc/passwd
/etc/gshadow
/etc/group

Most puppy users are tired of the `sudo` attitude of larger distros because there is always something .
A while back at linuxquestions.org I got tired of the pro sudo mainstream there.

I think GrumpyWolfe made a puppy-derivate MyWolfe or similar to be found at the Puppy Derivates Section which is running some LoginScreen with passwords .

I really think that it is keeping pupils stupid somehow to have more barriers than a screen in front of them .

To connect puppy to a larger bundle of a closed interior network I have no experience .

You would have to change the executable pathes or the permissions for some 1200 to 1800 executables, create /home directories , learn to work with commands like adduser , groupadd , su , sudo , chmod , passwd and so on . And the man support at puppy is mostly a shellscript somehow exec defaultbrowser http://www.google.XY/search/manpage $@ manualpage .

Much Luck !

Sidders released HanSamBen.

He is still about and can maybe help you out in removing
applications or hiding them.

This might work for you:

Edit:
Be sure to download current and previous BrowserLinux versions, as they are compiled with different kernels. Some computers won't work well (or at all) with certain kernels.

I apologize for not having more details about hardware. We have a hodgepodge of older computers I would like to put to use surfing the web. Ram probably ranges from 128 to 512 mb. I really don't know what's in the attic, but I plan on making it work with puppy.

I don't have to password protect, I just want to strip the os down so that it boots up with just a browser and maybe a word processor so that my students can ONLY view the test prep sites our school has purchased access to. Left to their own devices, a few students will screw up every computer if they have a chance.

A special thanks goes out for all the links and advice. I may try the "hide" shortcuts and see how they work. This would help if I need to grant "permissions" quickly for some students. Thanks again.

What exactly are you wanting to do as far as networking is concerned? Just have the ability to share files between the computers? Also what restrictions do you want to have on that?

Also what network hardware do you have? A switch or router that they are all connected to (that you have control of)? Just the school network (each separately plugged into the wall)? Wireless or wired?

PostPosted: Thu 13 Jan 2011, 00:03    Post_subject: Setting up the room  

@fhsteacher...Hello

Having help many schools in the past I think I understand what you would want to do within a classroom. To get you started with this group, let me ask a couple questions so that the members here can help you.
  • What class will be taught in the classroom(s) you set up?
  • Would each person in the class have his/her own computer at the desk they sit or will they be working in groups on single computers?
  • The research you will have them doing...will they be downloading files onto their computers or simply just looking at stuff on the internet?
  • Will the WordProcessing you will have them doing be handed in as printed hard copy or electronically transferred to you?
  • Would you expect each student to be able to save files in their names on your school network?
  • Will YOU be the primary person responsible for the management of the class's PCs?
  • What Operating Systems have you used in the past?
  • How long have you used ANY Linux?
  • And, do you already have a network at your school?
I think this will get us started to position to steer you effectively.

Hope this helps

Hi all

you could build a new puplet with woof and remove all the unwanted programs from the distro specs list then it would be easier to get the distro how you wanted it?

hope this helps

Hello fhsteacher.

I have the scripts etc for the disabling of menus etc, i could make them into a *pet and test it on Lupu. Its as cthisbear says, It wont actually remove the games and other apps you dont want, just hide them.

If you are using Google docs, would you need to save anything to the PC?. The shutdown script can be alterted to not save anything from the session (I have never used Google docs, i am assuming you can save stuff in the in the cloud).

I'll stop there

Let me know

And welcome to the Kennels Very Happy

PS. If you want to hide the menus, could you tell me which menus you want e.g Document, Network, Multimedia.

* A pet is a program installer in Puppy, one click and its done.

Well, given that Puppy works well as a frugal install (using a pupsave/lupsave), runs from a live boot CD, and can run from a USB drive, how about each student is given a basic pupsave that you set up (say, copy it from a CD, thus the master setup is read-only) and then they all boot from a CD.

Take the HDDs out of all the machines before you start... Make their HDD the flash drive they keep.

Then when they screw the system up, they only screw up their own OS...

Recopy the master lupsave, and they're back at their starting point.

The link given by Lobster contains safepup. Here is the link to the ISO and md5sum. It does what you want, and it is suitable for old PCs. There is a how-to at first boot to guide students.

If you want Java capability, you can rebuild the ISO using this pup_213.sfs. (If it is already installed to USB flash, then it is a matter of replacing/renaming the old pup_213.sfs.)

Having been toying with "network booting" hammer, all I see now is "nails" waiting for this "hammer" ... fhsteacher, since your student computers are all networked, why don't you use network booting (netboot) instead?

You can then use any standard puppy (choose the smaller ones). Most puplets are also netboot capable. Doesn't matter if the students wreck anything - at the next reboot, everything will come back as new. No need to worry about de-partitioned harddisk, scratched CDs etc. The computer won't even start if your netboot server isn't turned on. All you have to do is manage one netboot server (which also run on top standard puppy). Look for "PXE booting" in this forum if you're interested.

I think raffy, being the most senior netboot guru, can give you more hints for operational matters Twisted Evil
